Abstract
In a data bus system which links a plurality of users, user access to the bus is provided by an arbiter which responds to a plurality of user requests for bus access by employing an adjustable priority scheme for granting access. When a user has access to the bus, the arbiter updates user priority by assigning the lowest priority to the current user and upwardly adjusting the priorities of all currently-requesting users.
